On your journey through the Overworld, you stumble upon a quiet village, resting in the middle of a vast plains biome. Nothing seems out of the ordinary—until you step inside the Cleric's house.

There, something feels... off.

A small yellow carpet lies carefully in the center of the room, as if it were hiding something beneath it. You move it aside, uncovering a concealed trapdoor that leads into a narrow shaft. A lone ladder descends into the darkness.

Without thinking too much, you climb down.

What you don’t yet know is that this simple discovery will become something far greater than you could have imagined—leading you to hidden chambers in rare structures, through the depths of the Nether, and ultimately to face the Ender Dragon itself.

All to unravel an ancient alchemical mystery… and forge the most powerful block the world has ever known.

Extremely well made. There were numerous moments where i jumped off my chair seeing/understanding by myself some stuff. The fire and wind essences i was sure wouldn't work, how would you check if a fammable item is in lava before it burns or if a lightning strikes an item (which always deletes them)? I guess it's possible

Giving a new use to the dragon egg was very smart to do

Only difficulties i had were finding a village with a church (i looked at about 5 villages before spawning one myself) and understanding the items had to boil for a really long time before converting to the water essence and had to look in the code. Also (maybe im dumb) i had no idea how to progress after getting all the essences and resorted to searching stuff in the PMC page, and then the code. I saw the dragon egg check and then i remembered the thumbnail art of this page and it was sooo cool. But i don't think it would be that simple for other people

Last and least, the philostone fills only one bottle from a stack, deleting the others, and crushing any item that is not part of a recipe with the pestle deletes it too, so if i didn't know and accidentally threw my dragon egg in the cauldron...

(Also did you use the older versions of blockbench to make an animatedjava animation? Because when i made my small cutscene my old frame splitter program wasn't working and wanted to try aj but it was for older versions of blockbench)

Hey, thank you so much for your feedback!

The lava and lightning was actually pretty simple compared to some other things (like the Swamp Hut, I had to remake the whole structure because it was hardcoded 😭): The items take one tick to be destroyed.

Maybe I should've made the church structures a bit less rare...

And the researching and looking at the thumbnail was completely intended, my goal was to make it a bit more interesting so you don't already know what to do when downloading the pack.

The stone destroying all bottles in the stack is a bug I didn't have time to fix completely intended (trust).

I did use an old version of Blockbench using EnvBench: www.npmjs.com/package/envbench
